By analyzing multiple physical properties of the voice, Empath can identify emotions in real-time, regardless of language. Empath was first developed to assist with the delivery of mental healthcare services. In 2013, it was used in NTT DoCoMo's Tohoku reconstruction projects to evaluate care workers' mental health conditions. In addition to mental healthcare, Empath is utilized in various fields: robotics (with Yukai Engineering), lighting systems (with PHILIPS), virtual reality (with Intelligence, Ltd.), call centers (with TMJ), and employee assistance programs (with NTT DoCoMo).

It has been utilized in collaborative research programs with prestigious universities such as the University of Tokyo and Nara Institute of Science and Technology. Empath won the 2015 Japan Resilience Award first prize and an excellence award at the MCPC Awards in 2015.
